近日，日落後的西方天空令觀星愛好者欣喜不已，本月罕見的明亮行星群星璀璨。 2 月 18 日，在某些觀測點甚至能目睹水星從月球后方滑過的奇觀，此現象稱為月掩水星。這兩張傍晚時分的快照分別記錄瞭望遠鏡鏡頭下水星隱沒於新月背後的前後景象——這顆內行星在年輕月亮後方消失的罕見瞬間。 上圖可見明亮的水星隱約顯現在月球北緣（右側）——此時月球正被地球反照光照亮。下圖中，這顆明亮行星已從月球被太陽照亮的彎月後方浮現於更暗的天空。在俄克拉荷馬州薩利索以南地區觀測，此次水星月掩現象僅持續約 3 分鐘（影片）。但今夜您仍可欣賞行星巡遊盛景。 3 月 3 日：月全食
原文：Fans of the western sky after sunset have lately enjoyed this month's remarkable array of bright planets. Witnessed from some locations, on February 18 planet Mercury even appeared to slide behind the Moon, an event known as a lunar occultation. These two snapshots, taken in early evening skies show before and after telescopic views of the rare disappearance of innermost planet behind young Moon. The top panel finds bright Mercury just visible at the northern (right) edge of the earthshine-illuminated lunar disk. In the bottom panel the bright planet has emerged in darker skies beyond the Moon's sunlit crescent. As seen south of Sallisaw, Oklahoma, planet Earth, this lunar occultation of Mercury lasted only about 3 minutes (video). But you can still check out a parade of planets tonight. March 3: Total Lunar Eclipse
